With gcc 4.1:
drivers/lightnvm/core.c: In function ‘nvm_remove_tgt’:
drivers/lightnvm/core.c:510: warning: ‘t’ is used uninitialized in this function
Indeed, if no NVM devices have been registered, t will be an
uninitialized pointer, and may be dereferenced later. A call to
nvm_remove_tgt() can be triggered from userspace by issuing the
NVM_DEV_REMOVE ioctl on the lightnvm control device.
Fix this by preinitializing t to NULL.
